Cryogenic Liquids: Precautions and Safe Handling Procedures


Cryogenic liquids are extremely cold liquids that at normal temperature and pressure would be a gas. These very cold liquids provide a fluid media that is useful for researchers to preserve their sample materials and for laboratory experimental processes. This fact sheet provides a summary of the hazards and safe work practices for users of cryogens and can be referenced in the laboratory Chemical Hygiene Plan. The most common cryogens are nitrogen and helium.
